PILE FABRIC Filed Dec. 3, 1956 2 Sheets-Sheet 2 INVENTO PILE FABRIC W. E. Hoeselbarth, Carlisle, Pa., assignor to C. H. Masland & Sons, Carlisle, Pa., a corporation of Pennsylvania Application December '3, 1956, Serial No. 626,059

1 Claim. (Cl. 139-406) from a plurality of adjoining rows of pile loops of varying height in the same row, interspersed by a plurality of adjoining rows of cut pile, preferably having varying height in the same row.

A further purpose is to diversify a fabric by providing a plurality of adjoining rows of uncut loops having varying height in the same row and free from astrakhan ends interspersed by a plurality of adjoining rows of basket weave.

A further purpose is to provide a plurality of adjoining rows of cut tufts interspersed by a plurality of adjoining rows of basket weave.

Further purposes appear in the specification and in the claims.

In the drawings I have chosen to illustrate a few only of the numerous embodiments in which my invention may appear, selecting the forms shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.

Figure 1 is a diagrammatic top plan view of a weave according to the invention.

Figure 2 is a warpwise conventional weave diagram showing the weave at one area in Figure 1, and which suitably may be the entire weave of a carpet or rug.

Figure 3 is a conventional warpwise weave diagram :showing the weave in another area in Figure 1, which .permissibly may be the entire weave.

Figure 4 is a conventional warpwise weave diagram showing the weave in another area of Figure 1, which suitably may be the entire weave.

Figure 5 is a perspective of the face of the fabric show- .ing the constructions which appear in various areas of the pile. The fabric is in certain places broken away for clarity and illustration, and except for the very first row at the bottom, binder warps, stufier warps and back wefts are omitted to avoid confusion.

Describing in illustration but not in limitation and referring to the drawings:

It is very desirable to obtain a more pronounced texturing efiect than is possible by merely varying between high and low and cut and uncut pile. Efforts have been made in the past to pull out ends as in Hope U.S. Patent 1,287,997 and Davies U.S. Patent 2,704,091.

In accordance with the present invention, I produce a shaggy or astrakhan effect in certain areas, but without requiring the use of special wires (for example the hooks of Hope, or the flag wires of Davies) and without giving up the possibility of producing other effects in 2,929,413 Patented Mar. 22, 1960 the same area and still different effects in other areas. Thus unlike these prior art weaves, I can secure wavy loops amid the astrakhan ends and also wavy tufts, and as an alternative I can obtain in another area of the same fabric straight tufts interspersed by basket weave, or wavy loops interspersed by basket weave.

Accordingly the astrakhan effect is itself improved since it is placed in a setting of wavy loops and wavy tufts, and the contrast with other parts of the fabric is much increased.

Figure 1 illustrates the top of a fabric, suitably a Wilton carpet or rug, having area 20 which exhibit the Weave of Figure 2, areas 21 which exhibit the weave of Figure 3 and areas 22 which exhibit the weave of Figure 4. While Iillustrate all of these weaves combined in a single Wilton fabric, it will be evident that the invention is applicable to a velvet or Wilton weave conforming entirely to Figure 2, or to Figure 3, or to Figure 4 The weave of the invention employs two or more sets of pile warp ends 23 and 24, with as many wavy noncutting wires 26 and 27 introduced in succession, and as many desirably straight cutting wires 28 and 30 introduced in succession, as there are pile warp sets. Thus with two pile warp sets there are two wavy non-cutting wires 26 and 27 in succession and then two cutting wires 28 and 30 in succession, whereas if there are three pile warp sets there will be three wavy non-cutting wires and three cutting wires used in succession. The entire wire set is thus desirably a series of wavy non-cutting wires followed by a series of suitably straight cutting wires, then a series of wavy non-cutting'wires, etc.

While I refer to the wires 26 and 27 as wavy wires, it will be understood that they are of the well known type which have high and low portions along the top of the wire within the shed.

The cutting wires 28 and 30 are of the well known type which have cutters beyond the shed at the ends remote from the head.

The back of the fabric may be of any suitable type, suitably woven on a two-shot basis to consist of binder warp sets 31 and 32, a stuffer warp set 33, upper wefts 34 and lower wefts 35, as well known in Wilton and velvet carpet weaving.

In Figure 2 the pile warp sets 23 and 24 are successively raised over the cutting wires Sti and 28 to form pile loops 37 and 36 which are cut when the wires are Withdrawn, and then they are raised over non-cutting wavy wires 27 and 2 6 to form loops 40 and 38. In the form of Figure 2 the cutting wires as they are withdrawn cut the loops 37 and 3 6 to form straight cut pile tufts and then the wavy wires as they are withdrawn pull down on one side of the cut pile tufts to form wavy tufts at some points, while the loops 40 and 38 themselves are straight.

The loops which are formed over the high portions of the wires will exert no pull-down effect on the adjoining sides of the cut tufts, while the loops formed over the low portions of the wavy wires will exert the maximum pull-down effect, and since the wavy wires as shown are desirably high and have a high spread between their low and high portions, certain pile warp ends are completely pulled out from behind their anchorages under the upper wefts, causing astrakhan ends 41 and 42 to stick up amid the uncut loops. Ends which are intermediate between the extreme low ends and the high ends as initially formed over the wavy wire will not be fully dislodged or will pull down the cut tufts on one side and remain at maximum height after the wavy wires are withdrawn.

The effect shown in Figure 2 is varied in certain areas by forming a basket weave as the jacquard may demand. As shown in Figure 3, the loops 37 and 36 are there formed over the cutting wires 30 and 28, but in the arena having the wavy wires a basket weave is formed of loops 43 and 44 woven below two spaced upper'wefts and over one intermediate upper weft in staggered relation. When the wires-are pulled, straight rather than wavy cut pile is formed by loops 36 and 37 and the basket weave re= mains in two adjoining intermediate rows without astrakhan ends.

Figure 4 illustrates a form in which staggered basket weave loops 45 and 46 are formed by the jacquard mechanism under the cutting wires 30 and 28, while loops 4%) and 38 are woven over non-cutting wavy wires. In this case when the wires 26 and 27 are pulled out springing of the back of the carpet occurs and the resulting loops 40 and 38 are uncut wavy loops without astrakhan ends. 7

In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the fabric shown, and vI, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claim.

Having thus described my invention, what Icl'aim as new and desire to secure by Letters "Patent is:

A warp pile fabric having pile warp ends, binder warp ends and wefts interwoven together and forming a back, having a pile composed of a multiplicity of transverse 7 rows of pile projections composed of the pile warp ends,

the pile projections having anchorages beneath wefts in the back, certain of the weftwise rows of pile projections consisting of pile tufts at one warpwise side of the row of uniform height, and consisting of pile tufts at the other Warpwise side of the row of varying height in certain positions weftwise, with pile omitted in intervening positions weftwise between the pile tufts of varying height, and others of the rows of pile projections consisting of uncut pileloops of uniform height and intervening among the uncut pile loops, single astrakhan cut tufts having heights greater than the heights of the uncut pile loops, the astrakhan tufts being of varying height.
